` Application filed Junev s, 1925. serial No. 35,830.

To all wila/m, may concern:

-Be it known that 1, OSEARWALTER BECK-l ER, citizen of- Germany,residing at Stuttf, gart, Germany, have invented certainV new l sageskins by applying a convenient coagu.l

lating or hardening substance, such as animal orvegetable albumin, on aseamless -tu? bular ,fabric (or hose) in a thin ilm which,

after the said substance issuiiciently dried,

is removed therefrom. My copending U S. application, Serial No.35,829'led June 8, 1925 describes and -claimsthe process which thisapparatus is adapted to carry out. new device comprises an annularnozzle, consisting of a core preferably of circular cross `section andofa ring surrounding said core with a certain amount of clearance." By theaid of thisl noz'zle the said substance -isapplied preferably underpressure, the inner part or core of which nozzle serving as a =supportor guide'for the tubular fabric which is pulled through the nozzle whilethe said substanceis applied. The said core may be cylindrical but atone or more places is given an irregular shape, that is a shape'differing from the cylindrical which places' serve as a bearingforlsupporting members,' ,rollersY or the like, to which the forcesl orthe strains of the said core are transmitted. The variations in theshape of the core are such that the peripheral lengths of all crosssections are lessentially equal to that lof the i tubular fabric sectionso that folds of vthe latter are avoided., By these means the core willbe held floatingly in the same position without the supporting membershindering the longitudinal movement of the' tubular fabric. Consequentlyhoses or tubes of any desired length can be.used. This would not bepossible, if the corerwas supported from inside of the hose since thelength of the hose would be limited by that of the holding' members. v

The hose. or tubular fabric 1, to which th mass of animal or vegetablealbumin is applied by pressure, runs over a core 3 which is preferablyformed by a hollow cylinder pro-A jecting concentrically into a ringformed by the outlet opening 4 of a vessel 5. lBy the pipe 6 this vesselv5 is filled with albumin by means of pressure, the albumin passing `outthrough the annular space between the fabric surrounding the core 3 andthe outlet opening 4, these parts thus forming an annular nozzle.l Whenthe tubular fabric 1 is pulled along it is coated with a film ofalbumin.

is held by a tubular guide 7 of suiicient. size' to allow the fabric topass throughjthe strain, which it has to undergo by thehose or tubularfabric being pulled yalong the core lThe core 3 together, with thetubular fabric 4 there is provided above -or outside the vessel 5 someirregularities or variations in cross section of the core whilemaintaining the peripheral lengths of all cross sections sub, stantiallycgnstant. f In the construct-ion shown in Figs. 1 to 5 this variation inshape is provided by two flat parts 8 and 9 arranged at 90" to oneanother. Two pairs of rollers 1() and 11 are arranged to bear againstthe flat parts and thus constitute supporting members to taire up allforces or strains exerted by the operation on the floatingly held core.'.The liattened'paits 8 .and 9, as has beenV explained above aresoijdimensioned.

that, though differing in shape, the peripheral lengths of all crosssections are constant, and are equal to the peripheral length of a crosssection of the fabric. When care is taken, that all changes in shape ofthe core answer more or less this condition, the warrant is given, thatthe tubular fabric 1, in running over the co're, will not be folded 'butwill pass the guide rollers 10 and l1 smoothly. These rollers supportthe core merely from outside preventing any longitudinal movementthereof. The hose or tubular fabi-ic may bel given any desired lengthwithout necessitating any prolongation of the core 3.

A similar co'istruction is shown in Figs. 5 and 6. In this case the coreis provided with only one flattenedpart 12 which, however, is so bent,that one portion 13 being preferably horizontal, acts like a hook. Thisflattened part 12 can easily be supported by rollers 14C, 15, 16 and 17-in such a manner that all forces or strains of the core are transmittedto these rollers. Also in this case the` circumference of, the flattenedpart 13 is of such size, that the tubular fabric will pass thereonwithout folding.

The proper positioning of the core aside from the means just'describedwill also be assisted by the tubular Ofuide- 7, and the mass filled intothe vessel '5 being under pressure is compelled to completely surroundthat part of the core intermediate the opening et and the guide 7.
